An apparatus for activating an electrically or electronically controlled appliance from an energy-saving passive state, especially a locking system for locking and/or unlocking, in particular for an access and/or authorization and/or for other services for a wireless remote control, for controlling of front doors, for motor vehicles, or the like comprising a first device in the appliance and an associated second device designed in the type of an electronic key, an ID-transponder, a chip card or the like, wherein both devices for the intended operation have transmitters and/or receivers for electromagnetic signals is suggested which allows a large operation distance and a long battery lifetime of the second device. This is achieved in that the first device transmits a first cyclic repeated signal for the activation and/or authentication of the second device with a first data protocol within a first transmission time interval and with a first cycle time.
